NEED ASAP!!! find the average rate of change of f(x) =sin ^-1(x) over the interval [ 1/2 , sqrt 3 / 2]

Question

avg rate of change of f(x) =sin^-1(x) over the interval [1/2, √3 / 2] . (1 over 2 and √3 over 2)

do not use calculator and write answer in the form π /a (√b + 1) (π over a)

Answer 1

(π/3 - π/6)/(√3/2-1/2) = π/6/(√3-1)/2) = π/(3((√3-1)) = multiplying by (√3+1)/(√3+1), =

π/6(√3+1)
